OPTIMIZING THE OPERATING CONDITIONS OF GOLD ELUTION

The Kopanang Gold Plant is a modern plant that uses mill-leach-CIP- electrowinning processes. The gold from the electrowinning process is smelted centrally in another plant situated 5 km away from Kopanang. The quality of the final bullion is affected by the presence of base metals. This project focuses on the assessment of the existing operating parameters particularly with regards to elution

Activated carbon is not a homogeneous material The

ACTIVATED CARBON ADSORPTION 197 Carbons with a very high abrasion resistance are preferred, especially with the CIP and CIL processes, to avoid gold loss in carbon fines. The carbon has to be coarse to allow separation from the fine ore pulp (in the CIP and CIL processes) and free flow of solution in columns. As a rule 6 x 12,6 x 16, and 8 x 16 U.S. mesh carbons

Leaching & Adsorption Resource Book

The dissolved gold in solution is adsorbed onto activated carbon. When the carbon is loaded with enough gold it is removed from the circuit and sent to elution where the adsorption process is reversed and the gold is stripped off the carbon back into solution, electrowon and smelted into bars.

Carbon in pulp Wikipedia

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial applications where the presence of competing silver or copper does not prohibit its use.

Recognized methods of elution of strong-base resins use zinc cyanide, ammonium thiocyanate, or acidic thiourea. Although each method has advantages and disadvantages (Fleming and Cromberge, 1984), no single method seems to be appropriate for all cases.For example, Fleming (1989) used the zinc-cyanide method for a conventional strong-base resin (A161RIP) used at the Golden Jubilee RIP plant
